Hi Kookie,
You state that "you tried to enter the code three times and the radio is locked".
I Quote.
" Every Ford Audio system unit will accept only TEN (10)attempts at KeyCode entry,
Any further attempts will render the unit permanently inoperative. IE, The unit is " Locked out " until re-programed by Ford motor company Ltd.
With the Ignition on in position one (1) and the unit turned on, the unit will allow three (3) consecutive entries.
If Three (3) incorrect attempts are entered, A Thirty (30) minute delay is required during which time the unit MUST be left on, and the ignition switch MUST remain in position one (1).
The hyphens for the code will stay displayed.
After approx thirty (30) minutes the display hyphens will start to flash, This means that a KeyCode entry can be made.
This procedure is required between each successive entry, up to a total of Seven (7) further attempts."
BE WARNED. AFTER THIS, ANY FURTHER UNSUCCESFUL ATTEMPTS WILL LOCK THE UNIT..
Reading your post, it seems that you have another Seven (7) attempts. Best of luck.
Chadad.
